(1) Data have been aggregated to the county
level. Within each county, data for agencies reporting 6 to 11 months
of information were weighted to produce 12-month equivalents. Agencies
reporting less than 6 months of data were excluded from the
aggregation. Data from agencies reporting only statewide figures were
allocated to counties proportionate to their share of the state
population. (2) The codebook is provided by ICPSR as a Portable
Document Format (PDF) file. The PDF file format was developed by
Adobe Systems Incorporated and can be accessed using PDF reader
software, such as the Adobe Acrobat Reader. Information on how to
obtain a copy of the Acrobat Reader is provided on the ICPSR Web
site.
